Reshaping a line object

Line objects also have nodesA structural anchor point for a graphic object,
usually visible as a small square box superimposed over a graphic.
Nodes will be located separately at the start, at the end, and at
every change in direction within a graphic object. .,
but behave in a more restricted manner than Pipe, Polyline, or
Polygon objects.

A straight line can only consist of two nodes, (a
start node point and an end node point). These can be individually
selected to move the line to a different position, or at least
change its direction. The Line object does not support node adding.
To achieve the same result as adding a node to a Line object,
create a Polyline object instead. Deleting either of the (only two)
nodes of a Line object will delete the whole Line object
completely.
